Microsoft DevOps Engineer Expert AZ-400 Practice Question

An Azure Function app written in C# must read messages from an Azure Service Bus queue and write records to Azure SQL Database. The security team requires that:

  • No credentials are stored in source code or application configuration.
  • Credential rotation must occur automatically without administrator intervention.
  • The identity used must be deleted automatically when the Function app is deleted.

Which identity solution should you recommend?

  • Enable a system-assigned managed identity for the Function app and grant it the required Azure RBAC roles.

  • Use an Azure AD application that authenticates with a certificate managed outside Azure and reference the certificate thumbprint in the Function app.

  • Register an Azure AD application and store its client secret in Azure Key Vault for the Function app to retrieve at runtime.

  • Create a user-assigned managed identity and share it across all serverless workloads in the subscription.
